Original application filed May 8, 1916, Serial No. 96,197. Divided andthis application filed November 11, i 1916. Serial No. 130,789.

i To all whom alt-may concern:

Be it known'that I, CARL E. citizen of the United States, residing atNew York, in the borough of Manhattan and State of New York, haveinvented cer- AKELEY, a

. tam new and useful Improvements in Film- 9 Boxes for Motion-PictureCameras, of

.tended for use in that which the following is a specification. N

My invention relates to film boxes for motion picture cameras,particularly ingeneral type of camera disclosed in Letters Patent No.

1,181,201, granted to my assignee May 2,

1916, and is a division of an application for motion picture cameras,filed by me May s,'1916, Serial No. 96,197.

My invention has for its object to provide certain improvements in the'construction and operation of such film boxes, as will be, v

hereinafter more definitely pointed out and claimed, reference being hadto the accompanying drawings, in which:

Figure 1 is a side elevation of a camera and its base, partially brokenaway showing my improved'filin boxes in position thereon. Fig. 2 is'aview taken at a right angle to Fig. 1, the same being partly-in centralver tical tra sverse section.

Fig. is a top plan view of the camera, the'same being shown partlybroken away.

Fig. 4 is a detail side elevation of the plate supporting .the filmboxes.

Fig. 5 is a detailfview of a portion of the camera casing showing meansfor operating the film box'opening and closing mech-' I able legs otherthan those relating to the film boxes forming'no part of the presentinvention will not'be disclosed herein more fully.

The camera casing 3, which is supported by a spider 4, has an innercylindrical box 5 spaced therefrom, said casing being closed by aremovable front plate 6. Mounted in the cylindrical box 5 is a feedingfilm box 7 and a receiving film box 8, thesame being of the constructiondisclosed in an application for Letters Patent filed by me April 27,1916, Serial No. 93,928, and here need no further detail description.

Fixed in the interior of the cylindrical box 5 is a flat plate 9, shownin detail in Fig. 4, said plate having formed upon its outer facegrooved sockets 10 adapted to receive the outturned portions 11 of theplates bolted to the exterior of the film boxes 7 and 8 removably toretain the latter in their proper adjusted positions. And in order torotate the outer casings of said film boxes to the open or to the closedpositions without removing the same from the cylindrical box 5 andwithout removing the front plate 6, I provide toothed segments 12,

one for each film box, said segments'being slidable longitudinally in 9.Said toothed segments are in constant mesh with gear wheels 14 whoseshafts 15 are mounted in suitable bearings 16, said shafts projectingthrough slots 17 being bent into operating handles 18 on the outsidethereof, whereby said gears 14 may be rotated and in turn thereby shiftsaid segments 12 longitudinally. Said segments 12 have slottedprojections 19 adapted to engage the pins 20 of the film boxes 7 and 8,whereby one telescoping member of eachfilm box may be shifted withrespect to the other member to Open or close the film slot therein in amanner readily understood by reference to my application No. 93,928,hereinbefore referred to.

'Mounted in the front plate 6 of the camera are two knobs 21 and 22, onefor each of the film (boxes 7 and 8, said knobs having spring'pressedelements 23 engaging I film box, and in turn to the spool 26 thereoncarrying the film. By reference to Fig. 3 it will be seen that a-belt 27connects the lower knob 22 with a sheave 28, which is rotated by therotation of a handle 29, so that the motion of said sheave is impartedto said knob 22 and in turn is imparted to the .film spool 26 ofthelower or film reoeiving box 8, which will wind the film. thereon in theusual manner.

In Fig. 1, which shows the contents Of the camera casing 3 in elevation,the film 27 is in the front plate 6 and.

'22 will be imparted to the shaft 25 of its shown, its direction ofmovement being indicated by the arrows, said film leaving the feed box 7near the bottom of the latter, passing thence over the film drivemechanism (not shown), and on its return passing into the film-receivingbox 8, where it is wound upon the spool 26 therein by reason of'thedrive of said spool throu-gh the belt 27 and knob 22, in a mannerhereinbefore described.

Having thus described my invention, what 1 claim as'new and desire tosecure by Letters Patent, is

1. In a motion picture camera, a camera casing, a film box. mounted insaid casing and formed of telescoping sections adapted to rotate oneupon another to open or close the film slots therein, and meanspermanently mounted in said casing and adapted automatically to engagethe periphery of one of said sections when the filmbox is inserted,whereby said section may be shifted with respect to its complementalsection to open or close said film slots.

2. In avmotion picture camera, a camera casing, a film box mounted insaid casing and formed of telescoping sections adapted to rotate oneupon another to open or close the film slots therein, a projection onthe periphery of the outer one of said sections, and means extending tothe interior of the casing and adapted to be engaged automatically bysaid projection as the film box is positioned within said casing, saidmeans when actuated rotating said section to open or close the filmslots.

3. In a motion picture camera, a camera casing, feeding and receivinfilm boxes mounted in said casing, said lm boxes being formed oftelescoping sections adapted to rotate upon one another to open or closethe film slots therein, toothed segments adapted to engage projectionson one of the telescoping members of said film boxes, and gears operatedfrom the exterior of the camera casing for moving said segments and thusshiftin the sections of thefilm boxes to open or c ose their film slots.

In testimony whereof, I have hereunto set my hand this 1st day ofNovember, 1916.

CARL E. AKELEY.
